Wooden fire door and its manufacturing process

Abstract

The invention discloses a wooden fireproof door and a manufacturing process thereof. According to the technical scheme, the wooden fireproof door is characterized in that the wooden fireproof door comprises a door frame and a door leaf rotatably connected to the door frame; connecting plates are arranged on the side, rotatably connected to the door frame, of the door leaf; the ends, away from thedoor leaf, of the connecting plates are provided with rotating shafts; the ends, rotatably connected with the door leaf, of the door frame are provided with rotating seats; shaft holes matched with the rotating shafts are formed in the rotating seats; the positions, located on the two sides of the connecting plates, of the door leaf are provided with protective plates correspondingly, and the section of each protective plate is in an arc shape; arc-shaped grooves allowing the arc-shaped plates to be inserted into are formed in the door frame; and door closing devices for closing the door leafon the door frame are arranged on the rotating seats. When a fire disaster occurs, connecting pieces such as the connecting plates, the rotating seats and the door closing devices are not liable to bedirectly affected by fire behavior and thus not liable to lose efficacy, thus the fire-resistant time is long, the door leaf is not liable to be disengaged from the door frame when the fire disasteroccurs, and use reliability and safety are high.

Description

technical field [0001] The invention relates to the field of doors and windows, in particular to a wooden fireproof door and a manufacturing process thereof. Background technique [0002] In modern society, commercial buildings, factories, residential buildings, etc. often have a large area and building scale. In the event of a fire, if the fire spreads rapidly, it will cause incalculable losses. Therefore, it is necessary to install fire doors in such buildings becomes particularly important. When a fire occurs, the fire door can effectively prevent the fire from spreading, and minimize casualties and property losses. [0003] At present, the Chinese utility model patent with the notification number CN205349174U discloses a new type of wooden fireproof door, which includes a door frame, a door leaf frame, a door leaf main body, a fireproof hinge, a door closer and a fireproof lock; the doorframe is a rectangular frame structure, and the door leaf The frame is composed of ...

AI Technical Summary

Problems solved by technology

[0004] The fire-proof hinges and door closers of the above-mentioned new fire-resistant doors are exposed to the outside space. When a fire breaks out, the fire-proof hinges and door closers may be the first to fail due to the fire, which will affect the overall fire resistance and reliability.
